The authors describe the operation of an electro-optical photoluminescence quenching device based on CdSe nanoclusters formed using sequential ion implantation of Cd+ and Se+ in thermally grown SiO2 on silicon. A sample geometry consisting of a semitransparent gold... (Read more)

ZnO and CdSe crystals have similar hexagonal wurtzite structures with a contraction along the c-axis of the crystal, but contrary electronic fine structures for ZnO:Mn2+ (D < 0) and CdSe:Mn2+ (D > 0) have been found in EPR experiments. We demonstrate that the ground-state splitting in ZnO:Mn2+... (Read more)
